摘要（英）：

The invention discloses a 100kA lightning current generator for testing the impulse characteristics of a grounding device. The 100kA lightning current generator is characterized by comprising a generator, a direct-current charger and a surge generator body; an output end of the generator is connected with an input end of the direct-current charger, and an output end of the direct-current charger is connected with an input end of the surge generator body. The 100kA lightning current generator is a lightning current generator which can output a highest voltage of 1200kV, a lightning current peak of 100kA and a waveform of 8/20 microseconds or 2/1microseconds under the condition of a load greater than 5 omega. The 100kA lightning current generator can be applied to the testing of surge impedance of the grounding device, the research of a soil spark discharge phenomenon, high-current withstanding impulse experiments of grounding materials, electromagnetic compatibility experiments and other aspects, and can increase the precision and accuracy of the technical application.
